Abstract

A camera comprises a film feed device ( 9 ) for feeding a light-sensitive film arranged in the camera, a photographic shutter ( 10 ) for the image-forming exposure of the light-sensitive film and arranged in the optical path for the image recording, and a shutter release device ( 300 ) which before the shutter release adopts a readiness position and after the shutter release adopts a disengaged position and which has a spring reservoir ( 314, 315 ) that is tensioned by adjusting the shutter release device from the readiness position to the disengaged position in order to actuate the shutter ( 10 ), wherein the spring reservoir ( 314, 315 ) of the shutter release device ( 300 ) is not tensioned in the readiness position and in the disengaged position thereof and a return of the shutter release device ( 300 ) from the disengaged position to the readiness position is controlled by a control device ( 104, 106 ) that moves when feeding the film.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. A camera comprising 
       film feed means ( 9 ) for feeding a light-sensitive film disposed in the camera;  
       control means ( 104 ,  106 ) movable in accordance with film feeding;  
       a photographic shutter ( 10 ) arranged in the path of light for image recording on the film; and  
       shutter actuating means ( 300 ) comprising  
       manually operable exposure initiating means ( 308 ,  309 ,  312 ) for initiating actuation of said photographic shutter ( 10 ) for film exposure to light for image recording;  
       a shutter actuating member ( 317 ) movable between a first position representing a readiness condition prior to shutter actuation and a second position representing a condition after shutter actuation, so as to actuate said photographic shutter ( 10 ) in the course of said movement of said shutter actuating member from said first position to said second position; and  
       spring means ( 314 ,  315 ) provided, when being in a tensioned condition, for driving said shutter actuating member ( 317 ) so as to move from said first position to said second position and thereby to actuate said photographic shutter ( 10 );  
       wherein said spring means ( 314 ,  315 ) is in a detensioned condition when said shutter actuating member ( 317 ) is in its first position as well as in its second position, while temporarily being tensioned upon operation of said exposure initiating means ( 308 ,  309 ,  312 ); and  
       wherein said shutter actuating means ( 317 ) is movable from said second position back to said first position by said control means ( 104 ,  106 ) when being moved in accordance with film feeding.  
     
     
       2. A camera according to  claim 1 , wherein said spring means ( 314 ,  315 ) which is in detensioned condition when said shutter actuating member ( 317 ) is in its second position, is enabled to be temporarily tensioned and detensioned when said actuating member ( 317 ) is moved from said second position back to said first position. 
     
     
       3. A camera according to  claim 2 , wherein said shutter actuating means ( 300 ) further comprises a first follower ( 318 ) cooperating with said control means ( 104 ,  106 ) for tensioning said spring means ( 314 ,  315 ) upon operation of said exposure initiating means ( 308 ,  309 ,  312 ). 
     
     
       4. A camera according to  claim 2 , wherein said first follower ( 318 ) is provided for engaging a control surface ( 104 ) of said control means ( 104 ,  106 ) so as to pass over a disengagement edge ( 105   a ) of said control means ( 104 ,  106 ) upon operation of said exposure initiating means ( 308 ,  309 ,  312 ). 
     
     
       5. A camera according to  claim 3 , wherein said shutter actuating means ( 300 ) further comprises a second follower ( 319 ) cooperating with said control means ( 104 ,  106 ) when said shutter actuating member ( 317 ) from its second position is moved back to its first position upon movement of said control means ( 104 ,  106 ). 
     
     
       6. A camera according to  claim 1 , wherein said control means ( 104 ,  106 ) has at least one cam surface ( 107 ,  108 ). 
     
     
       7. A camera according to  claim 6 , wherein said at least one cam surface ( 107 ,  108 ) of said control said means ( 104 ,  106 ) is provided to be followed by a first follower ( 318 ) for tensioning said spring means ( 314 ,  315 ) upon operation of said exposure initiating means ( 308 ,  309 ,  312 ) and by a second follower ( 319 ) when said shutter actuating member ( 317 ) from its second position is moved back to its first position upon movement of said control means ( 104 ,  106 ). 
     
     
       8. A camera according to  claim 1 , wherein said spring means ( 314 ,  315 ) are formed by a resilient lever arm ( 313 ). 
     
     
       9. A camera according to  claim 8 , wherein said spring means ( 314 ,  315 ) and said shutter actuating member ( 317 ) are integrally formed by said lever arm ( 313 ). 
     
     
       10. A camera according to  claim 8 , wherein said lever arm ( 313 ) forming said shutter actuating member ( 317 ) and said spring means ( 314 , 315 ) comprises a first follower ( 318 )for tensioning said spring means ( 314 ,  315 ) upon operation of said exposure initiating means ( 308 ,  309 ,  312 ). 
     
     
       11. A camera according to  claim 10 , wherein said shutter actuating means ( 300 ) comprise a multiarm lever ( 301 ) including said lever arm ( 313 ) which forms said shutter actuating member ( 317 ) and said spring means ( 314 ,  315 ). 
     
     
       12. A camera according to  claim 11 , wherein said multi-arm lever ( 301 ) further includes said first follower ( 318 ).
